There is no standard voltage requirement throughout the world and the frequency, which is the number of times the electric current changes direction per second, is not the same in all countries. Moreover, plug holes, plug shapes, holes, sizes and sockets are also different in many countries.
Most electrical appliances bought overseas canít be connected to the wall outlets in your home country. There are only two main ways to solve this issue: you just replace (cut off!) the original plug and replace it with the plug that is standard in your home country, or you buy an foreign electricity adapter.
You need to purchase an adapter or converter, and not just a plug. A plug in the UK will only allow you to fit your item into the socket, but it will still turn out. Foreign electricity converters and adapters will convert power in the UK, or other countries, so that the appliance circuits will not burn out.
